PORTABLE SUPPORT AND POWER MECHANISM.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed December 2, 1907. Serial No. 404,771.

To all whom it may concern:

Be it known that I, JOSEPH C. STEINER, a citizen of the United States ofAmerica, residing in the city of St. Louis and State of Missouri, haveinvented certain new anduseful Improvements in Portable Sup orts andPower Mechanisms, of which the fo lowing is a full, clear, and exactdescription,reference being had to the accbmpanyingdrawings, formingpart of this specification.

My invention relates to a portable support and power mechanism foroperating clothes wringers and washing machines or the like, and it hasfor its object to provide a support and power mechanism of thischaracterwhich may be readily placed in connection with the device towhich power is to be communicated and be readily detached from a deviceit has served to operate in order that it may be applied to'anotherdevice that is to be operated.

Figure I is a top or plan view of my support and power mechanism. Fig.II is a side elevation of the support and power mechanism. Fig. III isan inverted view of the top of the stand by which my mechanism issupported with the legs of the stand shown in horizontal section andalso illustrating the clamp device employed to bind the lift screw thatsupports the table on. which the mechanism is mounted.

1 designates the top of a stand which includes, besides said top, legs 2that are adapted to be seated and moved upon a floor.

3 designates a table that is located above thetop of the stand and inwhich are mount-- ed vertically disposed stay pins 4 that extenddownwardly from the table and are loosely seated in the stand top 1.These stay pins serve to uide the table when moved vertically by t emeans to be presently described.

5 designates a lift screw that extends ver-' tically through the standtop 1 and is fitted in a threaded plate 6 that is mounted on said top,as seen in Fig. II. The lift screw 5 is provided at its lower' endwith-a hand wheel 7 and at its upper end is loosely fitted to the table3 in order that the screw may be rotated for the purpose of raising andlowering said table to place it at any desired degree of elevation,according to the height at which the mechanism supported by said tableis to be connected to a device that it is to operate.

8 designates an electric motor that is mounted on the table 3 and whichmay be of any' ordinary type. The flow of electrical current to thismotor is controlled through the medium of a switch 9 mounted upon thetable adjacent to the motor.

10 is a cone pulley fixed to the shaft of the motor 8 and which receivesa belt 11 by which power is transmitted from the motor.

12 designates a bracket attached to the table 3 and provided withhearing boxes 13 that are arranged parallel with the snaft of the motor8.

14 is the drive shaft of my power mechanism which is mounted in thebearing boxes 12 and which has fixed thereto a cone pulley 15 on whichthe belt 11 that leads from the motor shaft pulley 10 operates. Thepulleys 10 and 15 are made of cone form in order that the drive shaft 14of the power mechanism may be driven at varying speeds when the motor 8isin operation.

16 is a worm carried by the drive shaft 14.

17 designates the driven shaft of my power mechanism which is journaledinbearing boxes 13 supported by the bracket 12 and located at rightangles to the bearing boxes 13 in which the drive shaft 14 operates. Theshaft 17 is located at right angles to the drive shaft 14 and it hassecured to it a worm wheel 18 that is arranged in mesh with the worth 16carried by said drive shaft in order that power may be transmitted fromthe drive shaft to the driven shaft.

19 is a head fixed to the forward end of the driven shaft 17.

20 designates a connection member that is in the sha e of a sleeve. Thisconnection member is oosely united to the driven shaft 17 by a couplinbolt 21 that passes through the inner end of the member 20 and throughthe head 19 and the driven shaft to which said head is secured. Byattaching the connection member in the manner described, I

provide a universal joint between the connection member and the drivenshaft in order that said connection member may operate to drive a shaftto which it may be connected irrespective of whether or not the shaftthat is to be operated is in alinement with the driven shaft 17 of mymechanism.

The connection member 20 is provided at its forward end with a slot 20,see Fig. II, that is adapted to receive studs carried by a shaft towhich'the member is fitted, such as the shaft A of a clothes wringer, asillustrated in the drawings, and from which the connection member may bereadily disconnected, due to the simplicity of the attach- Figs. II andment of the connection member to said shaft. It is obvious thatattachment of the member 20 may be as readily made to the gearing shaftof a washing machine or other device, provided with studs adapted toenter the slots of the connection member.

For the purpose of retainin the table 3 in a position to which it mayave been elevated'for the proper adjustment of my mechanism relative toan object that is tobe operated thereb I provide a clamp shown m I andwhich is adapted to be brought into engagement with the lift screw 5by'whichthe table 3 is adjusted. This clamp comprises the followingparts: 21 is a bracket attached to the lower side of the stand top 1 and22 is a clamp bar fixed at one end to said bracket alongside of'the liftscrew 5. 23 is a yoke fixed to the end of the clamp bar 22 farthestremoved from the bracket 21 and which extends laterally from said bar.24 is a yielding clamp bar that is fixed at one end to the bracket 21This yielding clamp bar is located parallel with the clamp bar 22 andits end farthest removed from the bracket 21 is located within the yoke23. 25 is a lever ivotally mounted at 26 in the yoke 23 and the innerend of which is adapted to impinge a ainst the yieldin clam bar ,24.When the ever 25 is moved atera y to carry its inner end toward the freeend of the yielding 'clam bar 24, said clamp bar is moved towar the feedscrew and the two clamp bars 22 and 24 are drawn toward each other withthe result of causin them to grip the feed screw and hold it omrotation. The feed screw being held from rotation, acts to uphold thetable 3 in a stationary position ed on said table, a bracket su portedby in order that the motor and mechanism sup ported by the table may notpartake of a,

ownward movement while the mechanism is being operated to drive thedevice with which it is connected.

I claim: A 1. In a portable device of the character described, thecombination of a stand, a table supported by said stand, a motormountsaid .table, a drive shaft jour'na ed in said "bracket, a powerconnection member between said motor and said drive shaft,'a drivenshaft geared to said drive shaft, and a connection member carried bysaid driven shaft and adapted to be attachedto an object to be driventhereby said connection member being in the form of a sleeve havin auniversal joint connection with said drlven shaft, substantially assetforth.

2. In a portable device of the character described, the combination of astand, a table supported by said stand, a motor mounted on said table, abracket su ported by said table, a drive shaft journale in said bracket,a power connection member between said motor and said drive shaft, adriven shaft geared to said drive shaft, and a connection member carriedby said driven shaft and adapted to be attached to an object to bedriven thereby; said connection member being in the form of a sleevecontaining slots at its forward end, substantially as set forth.

3. In a portable device of the character described, the combination of astand having a top, a feed screw mounted in said top, a table supportedby said feed screw, power mechanism supported by said table, and a clampdevice secured to the top of said stand and adapted to gri said feedscrew, substantially asset fort 4. In a portable device of the characterdescribed, the combination of a stand having a top, a feed screw mountedin said top, a table supportedby said feed screw, power mechanismsupported by said table, and a clamp device secured to the top of saidstand and adapted to grip said feed screw; said clam comprising a pairof clamp bars, one of w 'ch is yieldable, a yoke secured to one of saidclamp bars, and a lever mounted in said yoke and adapted to move saidyield able clamp bar to said feed screw, substantially as set forth.

In presence of LILY Ros'r, H. G. COOK.
